ditanya g(x) =……? mohon plesae jawab dong kawan susah nie

f(g(x)) = (11x+16)/(-10x-9)
(g(x) +3)/(g(x)-4) = (11x+16) /(-10x-9)
(g(x) - 4)(11x + 16) = (g(x) + 3)(-10x - 9)
11x . g(x) + 16g(x) - 44x - 64 = -10x . g(x) - 9g(x) - 30x - 27

11x . g(x) + 16g(x) - 44x - 64 + 10x.g(x) + 9g(x) + 30x + 27 = 0

21x.g(x) + 25g(x) - 14x-37 = 0
21x.g(x) + 25g(x) = 14x + 37
g(x) (21x + 25) = 14x + 37
g(x) = (14x + 37)/(21x + 25)
